abstract
We have observed electromagnetically induced transparency (EIT) in rare-earth Pr3+-doped Y2SiO5over the spectral hole-burning temperature. The transmission of the probe laser beam is increased by a factor of exp(1.4) at 12 K when a coupling laser of 1.2 kW/cm2is applied to the system. The observation of EIT over the spectral hole-burning temperature in a rare-earth-doped solid represents important progress toward high-density echo-based optical memories at higher temperatures. 1999 Optical Society of America.
